Economic Efficiency in the Coastal Small-scale Fisheries in Lagos State, Nigeria
Jinadu, Olujimi O.
This study was aimed at assessing how efficient the small - scale fishing units in Lagos State, Nigeria use the
monetary inputs: costs of gear repairs, craft repairs, fuel, fishing losses, hired labor, and the residual costs of craft and gear.
Between January and December, 113 mechanized and 43 non-mechanized fishing units in 21 purposively chosen coastal
villages were surveyed bi-monthly through questionnaire administration. The input and output (earnings) data were
analyzed using the linear regression and Cobb-Douglas technique in monetary terms and Ordinary Least Square methods to
determine the elasticities of the fishing units in the wet and dry seasons. The regression output for the non-mechanized
category produced good fits for the yield models with adjusted R
2
values range of 0.88 in the wet to 0.98 in the dry seasons.
The mechanized category showed respective regression outputs of AR
2
of 0.94 and 0.62. The Durbin-Watson statistic
showed moderate multicollinearity amongst the chosen variable inputs. The non-mechanized category had three significant
explanatory variables in the dry season while five were significant in the wet season at the 0.05 level. The mechanized
category had significant F-ratio values at the 0.05 level in the seasons. The seasonal technical efficiency evaluated using
the chosen cost variables showed that there was inefficient combination of the inputs for optimal production.

An Economic Analysis To Sustainable Fisheries Management
Lokina, Razack B.
The coastal zone is a dynamic area surrounding the interface between land and sea. The coastal area and its resources
offer great benefits and opportunities for human use. Most coastal activities in Tanzania rely on the natural resources that the coast
offers (fishing, forestry, agriculture, tourism, mining, salt production mariculture etc). Therefore the condition of the coastal
ecosystem and social well being are closely linked. The challenge is to maintain and improve the resources base on which those
activities are dependent, while developing new economic opportunities in a way that benefits the people of the coast and the
nation as a whole. A major constraint is the inadequate institution and legal framework for coastal management. Economics is
about efficient allocation of resources. In normal cases market forces provide efficient allocation of resources. In fisheries,
however, market forces alone can not produce an efficient allocation. And as it has been evident in this paper there is already
overfishing in most of the offshore waters where majority of artisan fishernen concentrate. Thus calling for policy intervention to
rescue the stock from depletion. This should include licencing, seasonal closure; finding alternative economic activities to
fishermen, and community based conservation approach can as well be instituted.

Fishing Versus Farming in a Fresh Water Swamp in Trinidad in the Caribbean
Pemberton, Carlisle A.; Fridie, Marsha L.
This paper compares the status of fishing to farming in the Nariva Swamp, on the eastern coast of the island of Trinidad, in
the country of Trinidad and Tobago. This swamp is one of international significance, since it is a home to the endangered animal, the
manatee (Trichecus manatee). Also the swamp has a large population of two aquatic species of economic importance in Trinidad and
Tobago - the armored cat-fish or cascadura (Hoplosternum littorale) and the ampulariid snail or black conch (Pomacea urceus).
Residents of the area include in their diet the consumption of these species, as well as exploit them commercially. The paper is based
on two surveys in the swamp, one was of 99 occupiers of plots, to determine their economic activities and the other survey was of 33
households, to determine the importance of fish from the swamp in their diets. The analysis in the paper showed that farming was now
the dominant economic activity in the swamp, both in terms of income received as well as the amount of labor utilized. The residents
did consume fish from the swamp, but this fish was not the major source of protein. Poultry and poultry products, especially chicken
were the preferred protein sources. Farming was seen as a threat not only to fishing, but also to the native flora and fauna of the swamp
and the paper called for urgent studies of the impact of such extensive farming on the ecology of the swamp.

Economic effects of marine protected areas on small-scale fisheries: a case study of the trawl ban in the Gulf of Castellammare, Sicily
Whitmarsh, David B.; James, Carl; Pickering, Helen; Pipitone, Carlo; Badalamenti, Fabio; D'Anna, Giovanni
Despite growing interest in Marine Protected Areas, relatively little is still known in practice about their economic
impact or their distributional consequences for stakeholders. The present paper, based on an EU-funded project, attempts to
shed light on this issue by examining the economics of an artisanal fishery operating in an area of NW Sicily from which
trawlers have been excluded. The main issues examined relate to the financial performance of trammel net vessels, focussing
especially on (i) current profitability levels, (ii) financial implications of changes in catch rates, (iii) financial viability of
capital investment and (iv) comparative performance of vessels inside and outside the trawl ban area.
